Key Observations and Recommendations
- Tariff Increase Alert:
- All codes are subject to an additional 30.0% tariff after April 11, 2025.
-
This is a time-sensitive policy and may significantly increase import costs.
-
Material and Classification Clarification:
- Ensure the material form (raw fluoropolymer vs. sulfurized rubber) is clearly defined.
-
Confirm whether the product is a finished O ring or raw material for further processing.
-
Certifications and Documentation:
- Verify if customs certifications (e.g., material composition, origin, etc.) are required.
-
Maintain product specifications and technical data sheets for customs inspection.
-
Cost Implications:
- The base tariff varies between 0.0% and 2.9%, but the total tax rate is 55.0% to 57.9% due to additional tariffs.
- Consider alternative sourcing or tariff exemptions if applicable.
Proactive Advice
- Verify the exact product form (raw fluoropolymer, sulfurized rubber, or finished O ring).
- Check the HS CODE with customs or a classification expert to avoid misclassification penalties.
- Monitor the April 11, 2025 deadline for tariff changes and plan accordingly.
- Review import documentation to ensure compliance with all customs regulations.
